Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of communications, and particularly to a QoS (Quality of Service) policy control method, a core network device, a communication system, and a storage medium. Background Art
[0002] In the existing QoS mechanism, the CN (Core Network) device independently makes a coarse-grained QoS decision. Since this QoS decision cannot perceive and integrate the radio interface on the RAN (Radio Access Network) side and the services on the UE (User Equipment) side, the QoS decision may not match the radio interface and services, thereby reducing the data transmission performance and efficiency.
[0003] To alleviate problems such as data rate mismatch, service traffic discard, delay, and severe retransmission caused by the lag of this QoS decision, telecommunications operators propose to enhance the existing QoS mechanism through a two-way negotiation mechanism. The two-way QoS mechanism sends QoS negotiation information from the RAN device or the UE to the CN device, enabling the CN device to obtain reference feedback and effective adjustment when there is a serious mismatch between the QoS decision and the radio interface or services on the RAN side or the UE side, assisting the CN device to make a QoS decision that better matches the radio interface resources and service characteristics, which is conducive to achieving more accurate and finer-grained end-to-end QoS guarantee.

[0045] Figure 1 A flowchart of a QoS policy control method according to an embodiment of the present disclosure. In some embodiments, the following QoS policy control method is executed by a core network device.
[0046] In step 101, receive the QDAI (QoS Decision Aid Information) reported by the communication device.
[0047] In some embodiments, the core network device sends notification information to the communication device at a predetermined period, so that the communication device reports the QDAI according to the notification information.
[0048] In some embodiments, the communication device includes a user equipment or an access network device.
[0049] For example, when the communication device includes a user equipment, the QDAI includes at least one of a first transmission information set and a first reception information set, where the first transmission information set includes the identifier and transmission timestamp of any data packet in each uplink QoS flow sent by the user equipment, and the first reception information set includes the identifier and reception timestamp of any data packet in each downlink QoS flow received by the user equipment.
[0050] For example, when the communication device includes an access network device, the QDAI includes at least one of a third transmission information set and a third reception information set sent by the user equipment to the access network device, where the third transmission information set includes the identifier and transmission timestamp of any data packet in each uplink QoS flow sent by the user equipment, and the third reception information set includes the identifier and reception timestamp of any data packet in each downlink QoS flow received by the user equipment.
[0051] In step 102, determine the value of the QNI (QoS parameter corresponding Network performance Indicator) within the specified observation interval according to the QoS parameters in the QDAI.
[0052] In some embodiments, the specified observation interval includes a time unit (e.g., 2 seconds, 1 minute, 1 hour, etc.), a flow period, or a service life cycle.
[0053] In some embodiments, the QoS parameters include at least one of a minimum guaranteed bandwidth, a maximum one-way delay, a maximum round-trip delay, a maximum periodic delay jitter, a maximum packet loss rate, a maximum consecutive packet loss rate, and a maximum packet reordering rate.
[0054] In some embodiments, as shown in Table 1, the QoS parameter set includes parameters such as Priority, Minimum guaranteed bandwidth, Maximum one-way delay, Maximum round-trip delay, Maximum delay window, Maximum cycledelay variation, Maximum packet loss ratio, Maximum consecutive packet loss ratio, Maximum packet reordered ratio, etc., covering six dimensions of priority, bandwidth, delay, delay jitter, packet loss ratio, and packet reordering.
[0055]
[0056]
[0057] Table 1
[0058] It should be noted that the minimum guaranteed bandwidth represents the minimum bandwidth that the network should provide, which is the lower bound requirement for bandwidth. The maximum one-way delay represents the maximum one-way delay that the data stream can tolerate during network transmission, which is the upper bound requirement for one-way delay. The maximum round-trip delay represents the maximum round-trip delay that the data stream can tolerate during network transmission, which is the upper bound requirement for round-trip delay. The maximum delay window is the range of one-way delay that the data stream can tolerate during network transmission, which is the lower and upper bound requirements for one-way delay (the delay window also reflects the requirement for delay jitter). The maximum cycledelay variation represents the maximum difference in one-way delay that can be tolerated between adjacent cycles of a periodic data stream, which is the upper bound requirement for delay jitter. The maximum packet loss ratio represents the ratio of the maximum number of packets lost that the data stream can tolerate within the observation period to the total number of data packets, which is the upper bound for the packet loss ratio. The maximum consecutive packet loss ratio represents the ratio of the number of consecutively lost packets with adjacent sequence numbers that the data stream can tolerate within the observation period to the total number of data packets, which is the upper bound for the consecutive packet loss ratio. The maximum packet reordered ratio represents the ratio of the number of out-of-order packets that the data stream can tolerate within the observation period to the number of successfully transmitted packets, which is the upper bound for the reordering ratio.
[0059] In some embodiments, when the QoS parameter includes the minimum guaranteed bandwidth, the QNI includes the bandwidth occupied by the data stream.
[0060] In some embodiments, when the QoS parameter includes the maximum one-way delay, the QNI includes the one-way delay of the data stream.
[0061] In some embodiments, when the QoS parameter includes the maximum round-trip delay, the QNI includes the data flow round-trip delay.
[0062] In some embodiments, when the QoS parameter includes the maximum periodic delay jitter, the QNI includes the periodic delay jitter.
[0063] In some embodiments, when the QoS parameter includes the maximum packet loss rate, the QNI includes the packet loss rate.
[0064] In some embodiments, when the QoS parameter includes the maximum consecutive packet loss rate, the QNI includes the consecutive packet loss rate.
[0065] In some embodiments, when the QoS parameter includes the maximum packet reordering rate, the QNI includes the packet reordering rate.
[0066] It should be noted that the bandwidth occupied by the data flow is the ratio of the number of data flow bits to the duration of the observation interval. The one-way delay of the data flow is the difference between the maximum reception time and the minimum transmission time. For example, for data flow i, the one-way delay is the difference between the maximum value of {RT(i,n)|n = 1, 2, …, N(i)} and the minimum value of {ST(i,n)|n = 1, 2, …, N(i)}, where N(i) represents the total number of data packets of the data flow. The round-trip delay of the data flow is the sum of the uplink and downlink one-way delays. The periodic delay jitter is the difference in delay between adjacent periods of the data flow in the service period. The packet loss rate is the ratio of the number of received data packets to the number of sent data packets. The consecutive packet loss rate is the ratio of the number of data packets in the packet loss period to the number of sent data packets. The packet loss period is the time period during which packets with consecutive sequence numbers are lost. The packet reordering rate is the ratio of the number of data packets with inconsistent reception order and transmission order to the number of received data packets.
[0067] In some embodiments, when the QDAI includes the first transmission information set, the value of the QNI within the specified observation interval is calculated using the QDAI and the second reception information set, where the second reception information set includes the identifier and reception timestamp of any data packet in each uplink QoS flow received by the core network device.
[0068] In some embodiments, when the QDAI includes the first reception information set, the value of the QNI within the specified observation interval is calculated using the QDAI and the second transmission information set, where the second transmission information set includes the identifier and transmission timestamp of any data packet in each downlink QoS flow sent by the core network device.
[0069] In some embodiments, when the QDAI includes a third set of transmission information, the value of the QNI within a specified observation interval is calculated using the QDAI and a fourth set of reception information, where the fourth set of reception information includes the identifier and reception timestamp of any data packet in each uplink QoS flow received by the core network device.
[0070] In some embodiments, when the QDAI includes a third set of reception information, the value of the QNI within a specified observation interval is calculated using the QDAI and a fourth set of transmission information, where the fourth set of transmission information includes the identifier and transmission timestamp of any data packet in each downlink QoS flow sent by the core network device.
[0071] In step 103, when the value of the QNI is not within the specified range of the QoS parameters, the QoS policy is re - formulated according to the QDAI.
[0072] In step 104, the re - formulated QoS policy is issued.
[0073] In some embodiments, when the value of the QNI is within the specified range of the QoS parameters, the current QoS policy remains unchanged.
[0074] In the QoS policy control method provided in the above embodiments of the present disclosure, by enhancing the QoS parameters, multi - dimensional fine - grained QoS guarantee can be supported.
[0075] Figure 2 This is a schematic structural diagram of a core network device according to an embodiment of the present disclosure. As Figure 2 shown, the core network device includes a memory 21 and a processor 22.
[0076] The memory 21 is used to store instructions. The processor 22 is coupled to the memory 21, and the processor 22 is configured to execute the methods involved in any of the embodiments as Figure 1 described.

[0086] Embodiment 1:
[0087] In this embodiment, as Figure 4 shown, the UE reports QDAI, and the UE sends an uplink QoS flow.
[0088] In step 401, the UE records the identifier and the transmission timestamp of any data packet in each uplink QoS flow to generate a transmission information set SI.
[0089] For example, if the UE records the identifier of the nth data packet in the ith uplink QoS flow, the corresponding recorded information is <i, n, ST(i, n)>, where ST(i, n) is the transmission timestamp.
[0090] In step 402, the core network device records the identifier and the transmission timestamp of any data packet in each uplink QoS flow to generate a reception information set RI.
[0091] For example, if the core network device records the identifier of the nth data packet in the ith uplink QoS flow, the corresponding recorded information is <i, n, RT(i, n)>, where RT(i, n) is the reception timestamp.
[0092] In step 403, after the uplink QoS flow is sent successfully, the core network device sends a notification message to the UE.
[0093] In step 404, the UE sends the QDAI to the core network device according to the notification message.
[0094] It should be noted that the QDAI includes QoS parameters and a transmission information set SI.
[0095] In step 405, the core network device calculates the QNI value according to the QDAI and a received information set RI.
[0096] In step 406, if the QNI value is not within the specified range of the QoS parameters, the core network device re-formulates the QoS policy according to the QDAI and sends the re-formulated QoS policy to the access network device.
[0097] Embodiment 2:
[0098] In this embodiment, as Figure 5 shown, the UE reports the QDAI, and the core network device sends the downlink QoS flow.
[0099] In step 501, the core network device records the identifier and transmission timestamp of any data packet in each downlink QoS flow to generate a transmission information set SI.
[0100] For example, if the core network device records the identifier of the nth data packet in the ith downlink QoS flow, the corresponding recorded information is <i, n, ST(i, n)>, where ST(i, n) is the transmission timestamp.
[0101] In step 502, the UE records the identifier and transmission timestamp of any data packet in each downlink QoS flow to generate a received information set RI.
[0102] For example, if the UE records the identifier of the nth data packet in the ith downlink QoS flow, the corresponding recorded information is <i, n, RT(i, n)>, where RT(i, n) is the reception timestamp.
[0103] In step 503, after the downlink QoS flow is sent successfully, the core network device sends a notification message to the UE.
[0104] In step 504, the UE sends the QDAI to the core network device according to the notification message.
[0105] It should be noted that the QDAI includes QoS parameters and a received information set RI.
[0106] In step 505, the core network device calculates the QNI value according to the QDAI and the transmission information set SI.
[0107] In step 506, when the QNI value is not within the specified range of the QoS parameter, the core network device re-formulates the QoS policy according to the QDAI and sends the re-formulated QoS policy to the access network device.
[0108] Embodiment 3:
[0109] In this embodiment, as Figure 6 shown, the access network device reports the QDAI, and the UE sends an uplink QoS flow.
[0110] In step 601, the UE records the identifier and the transmission timestamp of any data packet in each uplink QoS flow to generate a transmission information set SI.
[0111] For example, if the UE records the identifier of the nth data packet in the ith uplink QoS flow, the corresponding recorded information is <i, n, ST(i, n)>, where ST(i, n) is the transmission timestamp.
[0112] In step 602, the core network device records the identifier and the transmission timestamp of any data packet in each uplink QoS flow to generate a reception information set RI.
[0113] For example, if the core network device records the identifier of the nth data packet in the ith uplink QoS flow, the corresponding recorded information is <i, n, RT(i, n)>, where RT(i, n) is the reception timestamp.
[0114] In step 603, after the uplink QoS flow is sent, the UE sends the transmission information set SI to the access network device.
[0115] In step 604, the core network device sends a notification message to the access network device.
[0116] In step 605, the access network device sends the QDAI to the core network device according to the notification message.
[0117] It should be noted that the QDAI includes the QoS parameter and the transmission information set SI.
[0118] In step 606, the core network device calculates the QNI value according to the QDAI and the reception information set RI.
[0119] In step 607, when the QNI value is not within the specified range of the QoS parameter, the core network device re-formulates the QoS policy according to the QDAI and sends the re-formulated QoS policy to the access network device.
[0120] Embodiment 4:
[0121] In this embodiment, as Figure 7As shown, the access network device reports QDAI, and the core network device sends downlink QoS flows.
[0122] In step 701, the core network device records the identifier and transmission timestamp of any data packet in each downlink QoS flow to generate a transmission information set SI.
[0123] For example, if the core network device records the identifier of the nth data packet in the ith downlink QoS flow, the corresponding recorded information is <i, n, ST(i, n)>, where ST(i, n) is the transmission timestamp.
[0124] In step 702, the UE records the identifier and transmission timestamp of any of the above data packets in each downlink QoS flow to generate a reception information set RI.
[0125] For example, if the UE records the identifier of the nth data packet in the ith downlink QoS flow, the corresponding recorded information is <i, n, RT(i, n)>, where RT(i, n) is the reception timestamp.
[0126] In step 703, after the downlink QoS flow is sent, the UE sends the reception information set RI to the access network device.
[0127] In step 704, the core network device sends a notification message to the access network device.
[0128] In step 705, the access network device sends QDAI to the core network device according to the notification message.
[0129] It should be noted that QDAI includes QoS parameters and the reception information set RI.
[0130] In step 706, the core network device calculates the QNI value according to QDAI and the transmission information set SI.
[0131] In step 707, in the case where the QNI value is not within the specified range of the QoS parameters, the core network device re-formulates the QoS policy according to QDAI and sends the re-formulated QoS policy to the access network device.
